The enclosure has 1/2 inch cement board screwed directly on top of the wood studs. The tile (4x4 irregular edge) is going to be installed directly onto the cement board. Is this adequate protection for moisture.
Additionally the cement board extends about 3 inches beyond the dry side of the shower enclosure where it butts up against green board and had been feathered in to the greenboard with mesh tape and drywall mud.
Is there any problem with this type of installation.
